Objective To observe the effect of high-frequency repetitive transcranial magnetic stimulation on hemiplegic shoulder pain during convalescence of stroke.Methods A total of 40 patients with hemiplegic shoulder pain during convalescing stroke who were hospitalized in Rehabilitation Medicine Department of Jiaxing Second Hospital from January 2021 to June 2022 were selected and randomly divided into treatment group(rTMS group)and control group(sham rTMS group),with 20 cases in each group.Both groups were given anti-inflammatory and analgesic drugs and conventional rehabilitation treatment.On this basis,the treatment group was combined with rTMS treatment(stimulation frequency was 10.0Hz,stimulation intensity was 80%resting motor threshold,stimulation time was 10s,interval was 50s,total treatment time was 20 minutes,once a day from Monday to Friday,continued treatment 2 days apart,20 times as a course of treatment,a total of 4 weeks),while the control group received sham rTMS.Before treatment,2 and 4 weeks after treatment,numerical pain rating scale(NPRS)was used to assess the degree of shoulder pain,passive shoulder range of motion was measured by protractor,upper limb motor function of hemiplegic side was assessed by Fugl Meyer assessment upper extremity(FMA-UE),and the ability of daily living activities was assessed by modified Barthel index(MBI).Results After treatment,NPRS score of shoulder pain in 2 groups was significantly decreased compared with before treatment(P<0.001),passive shoulder motion and Fugl-Meyer upper limb motor function were significantly improved compared with before treatment(P<0.001),and the treatment group was significantly better than the control group,the difference between groups was statistically significant(P<0.05).The modified Barthel index in 2 groups was significantly improved compared with before treatment(P<0.001),but there was no statistical significance between 2 groups(P>0.05).Conclusion 10.0Hz high-frequency repetitive transcranial magnetic stimulation can significantly relieve hemiplegic shoulder pain during the convalession of stroke,improve the passive range of motion of the affected shoulder,and improve the upper limb motor function of the affected side,but the effect is not significant in improving the ability of daily living activities.
